NO, you use and iaito for iaido. Try not to correct someone unless you have your facts straight.
You can use a shinken for iaido, but you better have some flawless technique.
My reasoning for not using one of the raptors for iaido has to do with the leingth of the tsuka.
SSheperd is right in that the tsuka length of Raptor series would NOT be a wise choice for Iaido. Neither would a Shinken without approval from your sensei or for first time iaido student regardless of what the Sensei says.
